WINDING-ARBOR.

Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed December 30, 1915. Serial No. 69,386.

To all whom it may concern.

Be it known that I, LATIMER H. BALLOU, a citizen of the United States,residing at Lawrence, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Winding-Arbors; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to winding arbors for cloth winding machines.

The object of the invention is to provide a novel and improvedconstruction of winding arbor upon which cloth may be wound without theproduction of longitudinally extending wrinkles in the initialconvolutions of the roll, and which may be readily removed from thefinished roll.

To this end the invention comprises the features of construction andcombinations of parts hereinafter described and referred to in theclaims, the advantages of which will be apparent to those skilled in theart from the following detailed description of the preferred form of theinvention.

The invention will be readily understood from an inspection of theaccompanying drawings and the following detailed description of themechanism illustrated therein.

In the drawings, Figure 1 is an elevation showing so much of a clothwinding machine as is necessary to illustrate the application of thepresent invention thereto; Fig. 2 is a detailed sectional view showingthe left hand end of the arbor and its supporting socket; Fig. 3 is asectional elevation showing the right-hand end of the arbor and itssupporting socket; Fig. 4 is a sectional view on line 44, Fig. 2; Fig. 5is a sectional view on line 5-5, Fig. 3; and Fig. 6 is a detailed viewof therighthand end of the arbor.

In the drawings the inventionis shown as applied to a cloth windingmachine such as is commonly used for winding cloth into rolls or balesfor shipment. This machine comprises a fixed winding-shaft 2 and anopposed longitudinally movable winding.

shaft 4 which during the winding are driven in unison through gears 6and 8. The fixed shaft 2 is held from longitudinal movement in itsbearings by the collars 10, while the shaft 4 is provided with a groovedcollar 12 adapted to be engaged by the forked end of a lever (not shown)by which the shaft may be moved longitudinally as oocasion requires. Thegear 8 is keyed to the shaft 4 so that it will drive the shaft whilepermitting it to be moved longitudinally.

The winding arbor shown, which embodies the preferred form of theinvention, is adapted to be applied to the machine above described, andcomprises two oppositely tapered unconnected bars 14 and 16, and twosockets 18 and 20 which are constructed to receive the ends of the barsand hold them in winding relation. Each of the bars 14 and 16 isprovided with a slot 22 extending from its thin end nearly to itsopposite end. These slots register with each other and form a clothreceiving slot extending through the arbor when the bars are assembledand held together by the sockets 18 and 20. The recesses within thesockets are shaped to fit the ends of the assembled bars, and arepreferably provided with spurs 24 which project into the open ends ofthe slots 22 and maintain the sides of the bars in substantial alinementwith each other when subjected to the pressure of the cloth which isbeing wound thereon.

The fixed shaft 2 of winding machines as usually constructed is providedat its end with a plate 26, and. the holding .socket 18 of the arbor istherefore preferably made in the form of a recessed plate, and isprovided with screw holes adapted to register with the screw holes ofthe plate 26, and to receive the screws 28 by which the socket issecured to the plate. The socket 20 is preferably in the form of arecessed collar adapted to fit over the end of the longitudinallymovable shaft 4, and is secured thereto by a set screw 30.

To insert the bars 14 and 16 of the arbor in the machine, the shaft 40is withdrawn, and the thin slotted end of the bar 14 and the unslottedthick end of the bar 16 are inserted in the socket 18, after which theshaft 4 is advanced to engage the socket 20 with the slotted end of thebar 16 and unslotted end of the bar 14. The bars of the arbor are thussecured in assembled position with the tapered faces of the bars in en-I gagement, and with the slots 20 in aline ment and forming a clothreceiving slot which extends through the cloth supporting part of thearbor. This slot extends parallel to the surface and peripheral edges ofthe arbor, so that the cloth may be drawn smoothly and uniformly aboutthe arbor as the initial convolutions are Wound thereon. This avoids theformation of folds or Wrinkles extending transversely of the cloth andlongitudinally of the arbor, such as are formed in Winding the initialconvolutions about an arbor having a cloth receiving slot which isinclined or at an angle to the surface of the arbor, as in theconstruction of arbor shown and described in applicants prior Patent No.983,600. While the cloth receiving slot is parallel to the clothsupporting surface of the arbor, the bars of the arbor may be readilyremoved Without disturbing the inner end of the cloth by reason of theoppositely tapered form of the bars, and the provision of the open-endedslots extending through the thin ends ofthe bars. The bar 14 may beprovided With a crosspiece 32 to assist in Withdrawing the bar.

While it is preferred to employ the specific construction andarrangement of parts shown and described, in embodying the invention inan arbor construction Which may be readily applied to existing Windingmachines, it Will be understood that this construction and arrangementare not essential to the broader features of the invention, but may bevaried or modified Without departing therefrom.

Having explained the nature and object of the invention, andspecifically described one form of mechanism in Which it may beembodied, What is claimed is 1. A Winding arbor for cloth Windingmachines comprising a pair of unconnected oppositely tapered bars, eachof Which is slotted from its thin end nearly to its opposite end, andsockets Within Which the ends of the assembled bars fit adapted to besecured to the opposed ends of the Winding shafts of a Winding machine.

2. A. Winding arbor for cloth Winding machines comprising a pair ofunconnected oppositely tapered bars, each of Which is slotted from itsthin end nearly to its opposite end, and sockets for the ends of theassembled bars provided With spurs entering the open ends of the slotsand adapted to be secured to the opposed ends of the Winding shafts of aWinding machine.
